Overview
Project Background E-Science Background The NOM e-Science Collaboratory Invitation to Test, Contribute, Participate Summary
Background
Small NSF-ITR involving Computer Scientists and Environmental Scientists
Focus: “Stochastic Synthesis: Simulating the environmental transformations of NOM”
IT Focus: e-Science, Web-Based Science, Agent-Based Simulation, Data Mining
E-Science Background
NSF Cyberinfrastructure Program Sensor networks Large amounts of data => discovery through
datamining Online linked data repositories Online analysis programs: search, extraction,
matching, simulation, visualizations, etc.
E-Science Background (cont) WWW Telescope Virtual Observatories
NASA Skyview US National Virtual Observatory International Virtual Observatory Alliance
More and more research done without every using a telescope => use of distributed data already collected
E-Science Background (cont) NCBI (National Center for
Biotechnology Information)

Questions?
Has this research community begun to participate in the e-Science initiatives?
Would this community benefit from e-Science initiatives?
Is this community interested in an e-Science initiatives?
Is this community willing to experiment?
